Member Function Documentation

double TREND2D::AddTrend	(	double	x,
		double	y,
		double	value
	)			const

Add trend to value at specified coordinates.

ERRVALUE TREND2D::Compute	(	const PARM &	parm,
		const RVC::OBJITEM &	ObjItemRaster,
		const RVC::OBJITEM *	pObjItemMask = 0
	)

Compute trend using raster and optional mask specified by OBJITEM.

Parameters:

	parm	Parameters to compute from
	ObjItemRaster	Raster
	pObjItemMask	Optional mask

ERRVALUE TREND2D::Compute	(	const PARM &	parm,
		RVC::RASTER &	ObjRaster,
		RVC::RASTER *	pObjMask = 0
	)

Compute trend using open raster and optional mask.

Mask must be binary and same size as raster.

Parameters:

	parm	Parameters to compute from
	ObjRaster	Open raster
	pObjMask	Optional open mask

double TREND2D::GetGlobalOffset

(

)

const [inline]

Get global offset for computed trend.

double TREND2D::GetGlobalScale

(

)

const [inline]

Get global scale for computed trend.

const PARM& TREND2D::GetParm

(

)

const [inline]

Get parameters used in last trend computation.

double TREND2D::GetValue	(	double	x,
		double	y
	)			const [inline]

Get raw trend value at specified coordinates.

double TREND2D::SubtractTrend	(	double	x,
		double	y,
		double	value
	)			const

Subtract trend to value at specified coordinates.
